I am very interested in this - I have believed since the beginning it was based on custody (or rather, he wanted her to himself and to hurt KB would be a bonus IMO). Why murder when so much is at stake? I've thought of other motives, money, hate, control, power, evilness, betrayal, etc. but I just come back to the baby. Although if KB was seeing someone, that would make him very angry IMO not because he wanted her - he did not want anyone else to have her and be happy - and if he did use a baseball bat that would help explain the violence IMO. I also think he used KK and do believe he told her to come clean up her mess in that phone call 11/22. JMO
